the planner fails when i associate selector profiles in the transformation catalog
keg_root = (
                Transformation("keg_root", site="cori", pfn=exec_path, is_stageable=True)
                .add_pegasus_profile(
                    cores="1",
                    runtime="1800",
                    glite_arguments="--qos=regular --constraint=haswell --licenses=SCRATCH",
                )
                .add_selector_profile(execution_site=, pfn=, grid_job_type=)
